We have all done this. You have on your favorite push-up bra or are wearing a low-cut shirt and a guy walks by and you push the ladies out. But not in the super-obvious-pin-up-shoulders-way-back kind of way. Nope, instead you do the ultimate secret girl move: you tighten your neck, take a deep breath breath and push your shoulders down slightly. Amazingly, this works brilliantly. It makes you look like you have gigantic ta-tas without giving away the fact that you're showing them off. Men are none the wiser.
Women, on the other hand, can tell when another girl is doing The Move. And we secretly applaud.
There's a (HILARIOUS) movie out now called She's Out of My League (it's reviewed on this site here and here). As the title suggests, the movie centers around a Perfect-10 girl and her nerdy boyfriend. The girl is played by Alice Eve who, besides being very pretty, has large-but-not-super-huge cans. In one scene, she gets undressed down to her bra and panties...and then pulls out The Move, making her boobies look enormous. The guy sitting across from us audibly said, "Whoa."
I'm trying to find a screencap of this to illustrate my point. Not to worry, though, she does The Move in some of the other scenes. Like this one.
Good work, Alice Eve. Nice tits.
